DESIGN OF REAL-WORLD ELECTRICAL ENGINEERING PRODUCTS USING FRONT-END 3D SIMULATION & OPTIMIZATION TECHNOLOGIES
POLOPT/ Laplace: Module for Electrostatic Analysis
POLOPT/Laplace is a BEM solver for Electrostatic problems highly validated at a numerous real-world engineering problems. It is particularly suited for the dielectric design of electrical equipment and is especially featured by:
- Incorporation of Streamer design criteria (BIL),
- Extensibility for additional design criteria if needed,
- Proven on real world devices,
- Integration in POLOPT suite offering synergy and Simulation-Based Design (SBD) for Dielectric problems
– Integration with CAD
– Integration with POLOPT/Optim
– Integration with POLOPT/SBD.
Laplace module within POLOPT family enables simulation of the complete class of problems appearing in the dielectric design of industrial apparatus. The wizard-driven menus in the CAD-integrated environment provides easy and user-friendly modeling of full-complexity problems including the following options:
- Charge density, field and potential distribution,
- Floating potential analysis,
- Distributed potential analysis,
- Field lines tracing,
- Space visualization,
- Unknown charge analysis.
